I tried the ber and red lacquer put on a piece of maple I had. It looks pretty cool!

I sprayed all the wood parts that will be painted with sanding sealer. This fills the grain up with a thick coat of stuff that can be sanded off level. This makes a good base to paint on and prevents a ton of lacquer from absorbing into the wood.

I found another gap in the headstock that needed to be filled with epoxy and sawdust.

The mahogany wood on the guitar body and guitar neck needs to be filled to smooth it out a bit (to make the painting easier).

I used a product made specifically for this and mahogany wood.

I also filled a chip in the ebony with some epoxy mixed with epoxy sanding dust.
